[0002] The electric motor of a new energy vehicle is the core of the power system, and its performance and durability are crucial to the operation of the vehicle. To improve the protection effect and maintenance convenience of the electric motor, a split type motor cover plate has emerged.

The hood type split cover plate can effectively isolate external environmental factors such as dust and moisture, and its split structure makes maintenance and replacement more efficient. The cover plate fixing strips are tightly connected to the hood type split cover plate through welding and are provided with multiple fixing holes, providing a stable mounting base.
